I think the OP is talking about the plastic clip, that connects to the other pipe/loop. I suspect it will be hard to procure while on the road.
I would consider a diy repair. Look at a piece of pvc piping (3/4"???) or coupler probably. Cut it to shape, it can be a loose fitting to the loop. Melt a hole for a mounting screw into the pipe. Inside the pipe consider a wine cork, for the screw to bit into. I'm sure the cork will expand and hold. As long as the corks is close to the same size.
